What is meant by overloading of an electrical circuit? Explain two possible causes due to which overloading may occur in household circuits? State one preventive measure that should be taken to avoid overloading of domestic electric circuits.

Explanation

**Step-by-Step Solution:**

1. **Definition of Overloading:**
Overloading of an electrical circuit occurs when the current flowing through the circuit exceeds the maximum capacity that the components in the circuit can handle. This excess current leads to increased heat production due to the resistance in the components, which can potentially damage them.

2. **Causes of Overloading:**
- **Cause 1: Connecting Multiple Appliances to a Single Socket:**
When several electrical appliances are plugged into a single socket, the total current drawn can exceed the socket's capacity. This can lead to overheating and potential damage to the circuit.
